® WorleyParsons <br /> resources&energy <br /> conditions of each application as listed in the Data Sheets. <br /> The valve body size will not be less than two pipe sizes smaller than the nominal inlet <br /> pipeline size, unless otherwise specified. <br /> Bellow seal bonnets will be used for highly toxic or volatile fluids. Teflon or approved <br /> non-asbestos alternate packing material may be used for temperatures between -40°F and <br /> 450°F. Grafoil packing will be used as a minimum for temperatures 450°F and above. <br /> Solenoid valves supplied with the control valves will have Class H coils 120 VAC UPS <br /> powered. The coil enclosure will normally be a minimum of NEMA 4 but will be suitable <br /> for the area of installation. Terminations will typically be by pigtail wires. <br /> 5.6.6.1 End Connections <br /> Steel valves with flanged ends will be in accordance with ASME B16.5. End to end <br /> dimension of each valve will be in accordance with the appropriate ISA Standards (i.e. ISA <br /> 575.03 and S75.04). <br /> All welding connections for valves 2-1/2 inches and larger in nominal size will be butt- <br /> welded. All welding connections for valves 2 inches and smaller in nominal size will be <br /> socket welded. All welding ends will be in accordance with ASME B 16.34 and B 16.25. <br /> Control valves in 300# class service and below will be flanged, except for Hydrogen, <br /> Natural Gas, Ammonia, steam and vacuum service. Where flanged valves are used the <br /> flange rating will match the pipe class specifications. <br /> All control valves 600# and greater will be furnished with weld end connections. <br /> For butterfly, ball, and similar body types, lugged or flanged bodies to permit dead end <br /> service will be provided unless otherwise specified. Wafer types that cannot be <br /> independently fastened to the field piping at both ends of the valve body will not be <br /> provided. <br /> 5.6.6.2 End extensions and Reducers: <br /> If the size of a welded end valve is different than the field pipe size, the valve will be <br /> furnished with shop welded concentric reducers matching the upstream and downstream <br /> pipe size, material and wall thickness. Shop welded end extensions will be provided for <br /> valves with body material that is different than the field piping material (such as alloy <br /> valve bodies to be welded into carbon steel pipelines or vice versa). End extensions will be <br /> a pipe section at least 6 inches (150 mm) long. End extensions and reducers will be factory <br /> installed on the valve body and stress relieved in accordance with ASME B31.1. End <br /> extensions and reducers will be shown on the valve drawing and included in the shop end- <br /> to-end or center-to-face dimensions. <br /> Lodi Energy Center 3.5- 10 LEC AFC <br /> 071608 Rev.A <br />
